Question

Explain the role adaptation plays in the perception of an afterimage. s. In the physiologic zero activity, circle the receptors that were firing more in each of the follow- ing situations: Hand initially placed in 40° water Hand initially placed in 20° water Hand shifted from 40° water to 30° water Hand shifted from 20° water to 30° water Warm receptors/Cold receptors Warm receptors/Cold receptors Warm receptors/Cold receptors Warm receptors/Cold receptors How did adaptation to temperature affect perception of temperature in the physiologic zero activity when both hands were placed in the 30° water? 6. Which solution is the less concentrated solution: 1:100 or 1:1000? Explain your answer

Explanation / Answer

4. Adaptation helps in positive as well as negative afterimage. In negative afterimage, the cones of the eyes adapted for the the overstimulation while in positive afterimage, the images are apppears as the same colour as the original colour.

5. Hand initially placed in 40 C = Warm receptor
   Hand initially placed in 20 C = Cold receptor
  Hand shifted from 40 C water to 30 C = Cold receptor
  Hand shifted from 20 C water to 30 C = Warm receptor.

6. 1:1000 solution is less concentrated because there is 999 parts of the solvent in the solution in comparison to the 99 parts of the solvent in the solution 1:100.
   Since it has more parts of solvent so it is less concentrated.
